Abstract: With the development of the construction industry, people's requirements for waterproof buildings and underground engineering anti-permeability technology and waterproof materials are also constantly improving. As a new type of inorganic rigid waterproof material, cementitious capillary crystalline waterproof material has the advantages of simple use method, good compatibility with the matrix, excellent waterproof effect and non-toxic environmental protection and are widely used. This paper summarizes the research process of mechanical properties, impermeability properties and self-healing properties of concrete by adding cementitious capillary crystalline waterproof material, and puts forward the future prospect of cementitious capillary crystalline waterproof material, so as to provide a basis for the future application of cementitious capillary crystalline waterproof material.
